Solar heating of the Earth's surface (land or water) heats the air above it, which becomes less dense that the air above it, and is displaced (rises). Once at higher altitudes, the air cools and sinks. The largest convection process transports heat and water vapor poleward from the tropics.

∙ 9y agoWhen air is heated, it becomes less dense than the cooler air above it, and rises (is displaced). As it moves upward, it is cooled, and the adiabatic pressure around it is lower, so it sinks again. Where water vapor is included in the air, this can create a phase change to liquid (clouds) at higher altitudes.

which diagram correctly indicates why convection currents form in water when water is heated
Which layer is most affected by conduction?
the layer that has convection currents is the mantle
Plate motion is caused partly by magnetic reversals convection currents continental drift or volacnic hot spots?
Convection currents
Light energy travels in the form of?
They travels in the form of waves and are filtered through the Earth's atmosphere.
What produced convection currents in Earth's atmosphere?
what produces convection currents in earth's atmosphere
What causes convection currents to form in Earth's atmosphere?
Solar energy
Which of the folling can form in the geosphere and carry heat from earth mantle toward the surface conduction currents infared currents convection currents or surface currents?
in the atmosphere.
The Sun heats Earth's atmosphere unevenly This causes convection currents to move in large circles in the atmosphere What is the result of convection currents in the atmosphere?
Study Island answer: Wind
What is the results of convection currents in the atmosphere?
Wind.
Why does convection take place in the atmosphere?
Convection take place because of convection currents
What is the relationship between convection currents in the ocean and convection currents in the atmosphere?
Which best explains the relationship between ocean currents and convection currents?(1 point) Responses Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents create a Coriolis effect that increases convection currents. Ocean currents create a Coriolis effect that increases convection currents. Convection currents use the Coriolis effect to generate ocean currents.
In what two places do convection currents form when the Sun heats Earth?
In what two places do convection currents form when the Sun heats Earth
What is Major source of energy that powers the convection currents in the atmosphere and ocean?
Vertical convection in both the ocean and atmosphere is caused by uneven HEATing.The source of energy for convection in the ocean and atmosphere is heating from the sun.
What causes currents in the ocean and atmosphere?
Warm air rising and cold air sinking in combination with the rotation of the Earth cause the various currents in the atmosphere.
What do the differences between the equator and the two poles produce?
convection currents in the atmosphere
How is thermal energy transferred in the atmosphere?
From the surface, it would be via convection currents
